Yes. I experimented with several 223 cases. Within 4 seconds the case necks glows red. I'm working on a drop mechanism and a chute for the cases to funnel into the coil. The logic board I got from MG in New Zealand works great! It also monitors current draw of the induction board to prevent a burnout. Its Arduino based with a few MOSFETs to drive servos and a stepper motor driver. All the work that needs to be done is well described in the link.
